![]() 4-wire resistive touchscreen uses the traditional method of using both electrode film layers to triangulate the location of the touch point. There are two main commonly used resistive touch technologies, analog 4-wire and analog 5-wire resistive touch. What are the most popular resistive touch technologies for Industrial Applications? This signals the touch controller the coordinates of the contact and registers it to the computer. The mechanism is very simple, when an object puts pressure on the screen, the space between the two transparent electrode films comes into contact and produces voltage change. This touchscreen is made up of a protective top film (usually made of clear polycarbonate), then a transparent electrode film made of ITO (indium tin oxide), spacer dots and insulators, another electrode film, and a glass bottom layer. Resistive touchscreen technology relies on placing pressure to register a touch. Expensive compared to resistive and surface capacitive touchscreens.Premio’s optional ‘Optical Bonding’ fills the air gaps between layers with resin to enhance durability, clarity, readability, and vibrancy under bright environments.Liquid, contaminant, and scratch resistant since modern protective layers use tempered glass.Optical clarity and readability due to the transparent build of PCAP.An example of a gesture is with the use of two fingers, users can zoom in/out on an application by using a pinching gesture. Because of the architecture of PCAP, it can detect multi-touch points simultaneously (Also known as 10-point touch) which allows for gesture functionality. The main benefit being multiple touch (multi-touch) point capabilities. There are many features that make PCAP the standard touchscreen technology for industrial applications. This reaction is relayed to a touch controller and pinpoints the location of contact and signals it to the computer. ![]() The electrode layer is made up of a checkered pattern of X electrodes and Y electrodes that change electrostatic capacity when a conductive object, in this case a finger, comes into contact. The construction of the PCAP touchscreen uses a top protective casing layer, usually made of insulating glass, then a transparent layer of electrode sensors that radiate an electromagnetic field that is sensing for conductivity, and finally a glass substrate. However, PCAP is the standard technology used for all capacitive touch screen applications. There are two types of capacitive touchscreen technologies, surface capacitive and PCAP (projected capacitive). What is a capacitive (PCAP) touchscreen and how does it work? Touchscreens are used for a multitude of applications such as kiosks, digital signage, automation, transportation, and much more. A touchscreen is a technology that allows a user to interact with a computer by touching the display screen without the use of a computer mouse.
